Wrong filter results for special characters on using Ignore Case

SA-57410

Summary



When a report definition is run and when a filter value has special characters, the results do not render in accordance with the filter.


Error Messages



Not Applicable


Steps to Reproduce

  1. Use a repeat grid with report definition loading the list of results.
  2. Create records which have special characters (such as 'ç , ã ) in the words.
  3. Search for the record using the word as the parameter.


Root Cause



If the filter has special characters, when the Ignore Case checkbox is unchecked and the report is run, the required rows are fetched. However, when the Ignore Case checkbox is checked, the results do not display.
When the filter condition has normal text value, the search works correctly. For special characters, the Case Insensitive search function does not work correctly.



Resolution



According to the logic, when the Ignore Case checkbox (present with the filters in the report definition) is checked, it invokes the UPPER function.
However, for DB2, the UPPER command does not work for accented or special characters. The UPPER function displays the value helló as HELLó.

Hence, comparison does not occur.
